chore(deps): astro 5->6 + vitest 2->3 — clear 11 of 12 Scorecard advisories

[harry-harish]

What

The astro 5→6 + vitest 2→3 major-bump PR that the Phase 4b override notes deferred to "its own PR". Rebased onto current main and built on its existing override strategy — clears 11 of the original 12 Scorecard advisories, leaving only the one esbuild residual main already documented as accepted.

Rebuilt from scratch on current main (the original branch was cut from a ~10-commit-stale main). The redundant "safe 4" follow-up (#130) was closed — those overrides are already on main.

Clears

• Astro 5 → 6 (apps/peek-docs, apps/tracelane-docs) — the 5 astro advisories (2pvr, 8hv8, j687, jrpj, xr5h; no 5.x backport exists).
  • Astro 6 moved to Zod 4, so @cubenest/docs-shared's recipeSchema is rebuilt on zod@^4.3.6 — content validation was silently failing otherwise (astro check flagged 32 cascading type errors).
  • Astro 6 needs Node >=22.12, declared in each docs app's engines (CI runs Node 24).
• Vitest 2 → 3 (root) — the critical GHSA-5xrq-8626-4rwp, and esbuild GHSA-67mh-4wv8-2f99 (retiring the vitest@2/Vite-5 toolchain drops the old esbuild@0.21.5). The @vitejs/plugin-react pin is now scoped to @wxt-dev/module-react (plugin-react 6 needs vite 7+ via vite/internal; WXT 0.20 stays on Vite 6).
• js-yaml (GHSA-h67p-54hq-rp68) — js-yaml@3 → 3.15.0 / @4 → 4.2.0, fixed within the 3.x line so @changesets/cli's safeLoad is preserved (the residual main was tracking).
• vite (GHSA-fx2h-pf6j-xcff, GHSA-v6wh-96g9-6wx3) → 6.4.3 via peek-extension's direct vite dep, replacing the vite@6 override (which rewrote vitefu/@tailwindcss-vite peers and broke strict-peer once astro@6/Vite-7 and the demo/Vite-8 entered the tree).

Residual (accepted, unchanged from main)

esbuild GHSA-g7r4-m6w7-qqqr — a global 0.28.1 pin breaks the WXT MV3 build (esbuild 0.28 can't lower for-of destructuring to chrome87/es2020); the advisory is esbuild-dev-server-only, never invoked in this build-only pipeline.

Verification

• pnpm audit → 11/12 cleared (only g7r4 residual).
• pnpm build green — incl. the WXT MV3 extension (esbuild 0.27.7 retained) and both Astro 6 docs sites.
• pnpm test — peek-mcp (35), peek-cli (25), peek-extension (45), rrweb-core, tracelane-core/security all pass under vitest 3. Remaining local failures are the pre-existing Windows-only @tracelane/report assets.ts path-guard tests (and tracelane-cli/detect) — they pass on CI Linux.

Warning

Review limit reached

@harry-harish, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 14 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
